Excellent story. Sometimes it felt a little slilted, a little jerky, but an excellent first look into a psychotic mind. From my personal research into this kind of mental illness, you could add in other details - let Pansy believe she sees him speaking to her, that she can see something in her eyes that leads her to believe he really wants her.

But fantastic none the less.

Author's Response: Yeah Sorry about that :) I wrote the story in one evening. But I will re-write soon :)
I will consider the possibility of writing a prequel, I think it is a good idea! :)
I'm so happy you liked it!

I see what you mean about the disalogue sometimes being stilted; this has a feel of being relaxed. The way you use long sentences give a relaxed feel, after all, if I've the time to type all this, doesn't it just feel...casual? Cut your sentences up. Feel, don't think. Take the train of thought and halt it. Curve it. Feel it turn. Turn again. Twist, a hard left.

Do you see the point I'm making?

I'm not sure how quickly she'd escalate, but it was a good exercise in noting how easy it is to slip into doing bad things for the sake of good. I'm really unsure that she'd throw in the killing curse; I suppose there's no parallel in your world.
